Hm, a crash inside the system-supplied getaddrinfo routine would suggest
that there's something wrong with the values we are passing into it.
The most likely bet is that we don't agree with libc about the layout of
"struct addrinfo". The configure script goes out of its way to be
paranoid about this, because we've seen it get confused by add-on
libbind installations (see also the head comment in
src/include/getaddrinfo.h) ... but I'll bet that AIX has found another
way to trip it up.
I can see from your trace that you are using the getaddrinfo code from
libc, but where is configure finding a header that declares struct
addrinfo?
